Abstract

The invention discloses a bone-promoting rubidium-titanium-tantalum composite material and its preparation method and application. The method performs sand blasting, acid treatment and alkali heat treatment on the titanium-tantalum composite material synthesized by plasma activation and sintering to modify the surface of the titanium-tantalum composite material. properties, and the surface of the surface-modified titanium-tantalum composite material is doped with rubidium salt through ion exchange, and finally the bone-promoting rubidium-titanium-tantalum composite material is prepared by high-temperature calcination. The material of the invention has good biocompatibility, does not have cytotoxicity, promotes cell proliferation, and has a good effect of inducing osteogenic differentiation of pre-osteoblasts. The material can effectively solve the problems of poor compatibility with the human body in clinical application of bone repair materials, and has broad application prospects in clinical bone repair.

Description

technical field [0001] The invention belongs to the field of biomedical materials, and in particular relates to a composite material containing rubidium, titanium and tantalum for bone formation and its preparation method and application. Background technique [0002] Knee osteoarthritis, hip fractures, and spinal degenerative diseases are all orthopedic diseases with a high incidence rate, and with the aging of the population, the incidence rate of the disease is increasing and younger. Titanium-tantalum composite materials are widely used in the field of clinical orthopedics because of their good mechanical properties, excellent biocompatibility and low cost. For example, joint replacement, spinal internal fixation and other common fracture treatment methods require the use of titanium-tantalum composite materials. material as a bone replacement material. However, since the titanium-tantalum composite material is a biologically inert material, the combination with the hum...
